Due to the lack of compatibility of Internet Explorer with the newest Internet technologies, Google announced in September a plugin called Chrome Frame which implements a number of new technologies existing in Google Chrome into the Microsoft browser.
However, the source code reveals that the plugin is not limited to Internet Explorer. The existence of the NPAPI protocol shows that the Chrome Frame engine could also work in browsers such as Firefox, Safari, Opera and others that support functionality.
According to Google OS, Google and partner companies may develop applications and ask users to install Chrome Frame. In this way, Google Chrome would run invisible within any other browser.
